Question

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.

Answer 1

Answer:

A

Explanation:

The correct answer would be that the sperms are changing chemical energy to kinetic energy.

In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells.  Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.

The correct option is A.
